So it is likely to be an ebook rather then a physical book and with ebooks many times you don't have to write nearly as much because you don't need to impress upon the potential reader that there is value in the book when they pick it up. You can simply put value into the book and price it reasonably and they will take a chance on it often because of the low price and pick up on the value as they read it. So it will likely be the length of a medium to long article. 

Still it will need a title, I plan to write about my blueprint for getting great deals (including At and Below Spot prices) for precious metals like Gold and Silver. If Platinum and Palladium are the way you want to go that is fine to but most people are going to key on the Gold and Silver I feel. 

Anyway I had mentioned it previously in a blog post but it would be a more in depth examination and step by step method for doing it. I know that a catchy title would help and I wanted to get some input.
